Assembly

1. Use bushing installation tool P/N 27-0460, to press in new axle bushings. This tool helps keep the bushing straight and keeps the inner diameter of the bushing correctly sized.
Note: The bushings are two different lengths. The side of the case with the thicker boss uses a longer busing to support the axle. The bushings should be ush with the inside of the case (Fig. 016). 3. Note: Some replacement axles have more than one hole that can be used to pin the sleeve to the axle. Refer to the original axle to identify the correct hole to use. Then drive a roll pin through the sleeve and axle (Fig. 017).

A. Tool P/N 27-0460 4. Using a seal protector, slide new seals down each side of the axle, Install the seal with the lip facing the transmission. The outer edge of the seal should be ush with the outside of the case. If a seal protector is not available, wrap a piece of cellophane around the axle (Fig. 018).
2. Clean the rust and dirt from the both ends of the axle. Wipe the inner diameter of the bushings with a clean cloth. Lightly oil the axle and insert it into the gearcase. When facing the front of the gearbox, insert the short end of the axle from left to right. Install the thrust washer, helical gear, and the sleeve and clutch jaw. Then push the axle through the other side of the case.

Controls
6. Install worm shaft in bearing. 7. Use a new gasket. Install the cover on the bottom case and start the 4 self-tapping screws. Do not fully tighten them. 8. Install the front and rear roll pins to align the cover and case. Then secure the 4 self-tapping screws. There are two control cables used with this system. One cable operates the engine kill switch and ywheel brake; the other controls the transmission.

Adjustment

The transmission cable is a standard lever type. Since the spring and pin on top of the transmission pushes the shift fork towards the engaged position, the cable pulls the shift arm to the rear to disengage the transmission. The adjustment point is on the mower housing just to the rear of the transmission. To adjust, pull the control to the rear (disengage). Go to the cable clamp/adjustment. Loosen the clamp, pull the cable to the rear until the shift lever is as far back as it will go. Hold it there and tighten the clamp (Fig. 021).

7. The transmission can be moved to the right until the short end of the axle clears the housing and the transmission can be removed (Fig. 031). Some models have the axle shaft retained by an end cap. The nut on the pulley can be removed now. The spacer under the pulley varies with the chassis and the length of the shaft on the pinion (Fig. 033). Remove the selftapping screws holding the cover on the transmission.

Before removing the parts from the case, note the quantity and location of the thrust washers (Fig. 034). Clean the gears in solvent and inspect carefully. Any damaged gear must be replaced. Also replace the mate for the damaged gear. When gears run together, they develop a wear pattern that will result in premature failure if only one gear is replaced. The exception for this is if the transmission has VERY little running time before failure. The axle has two roll pins through it. One connects the single spur gear to the axle (Fig. 036). The other pin aligns the axle and transmission case.

Remove the axle and intermediate shaft with the gears. The bearing in the cover should be sealed on both sides. Inspect the bearing and its seals for damage (Fig. 035). Replace as necessary. The bearing is pressed into the cover. Make sure bearing is fully seated.

Fig 036 3428-0016

Assemble with the correct number of thrust washers. Refer to the parts manual if there is any doubt at all. It is not possible to locate the shafts and bearings in the wrong location, due to differences in sizes.

GENERAL INFORMATION

This transmission was rst used on 22 steel deck models for 2002. It is used in both front wheel and rear wheel drive congurations. The bevel gear is reversed when used in the front drive versus the rear drive to change axle shaft direction of rotation. In both cases, the gears are in constant mesh. Clutching is done by rocking the transmission to tighten or loosen the drive belt (Fig. 040). The control cable will move the transmission to tighten the belt. When released, the weight of the transmission causes it to rock towards the engine to disengage.

Remove Transmission

1. Block the front of the mower up. There are two screws that secure the belt cover to the housing. They are accessed from the bottom (Fig. 042). 4. Remove the nut, washer, transmission pulley halves, and spacer. 5. Remove the belt guide. 6. Remove both front wheels; note there is a washer between the wheel and wheel cover. 7. To remove the wheel pinions, remove the klip ring and thrust washer. The pinion will now slide off the axle (Fig. 044). Note: The spring-loaded drive key is under the pinion.

Fig 042 MVC-482

2. Slip the belt out between the transmission pulley and belt guide. 3. Grip the axle with locking pliers and remove the locknut on the transmission pulley (Fig. 043)

Axle Assembly Tips
1. The same axle is used for both front and rear wheel drive models. There are two holes in the axle about one inch apart. Rear wheel drive models use the hole about 4-3/4 (12cm) from the end. Slip the gear on such that the teeth and the longest hub face the short end of the axle. Drive the pin into place. A double check is that neither of the pin holes should be visible when the gear is installed (Fig. 084). 3. Install the transmission bearings with the ange facing the gear (Fig. 085).

Fig 085

4. Fill the transmission approximately 2/3 full with #2 Lithium base grease (1.5 oz or 43gm). 5. Assemble the bearing, bearing retainer, HOC plate, spring arm, and pivot arm. Use two vise grips or clamps to compress the assembly so the snap ring can be installed (Fig. 086). Note: Install the snap ring with the sharp edge facing away from the spring arm.

Fig 117 3428-0065

The shift keys are retained on one end by the shift collar. Movement of the shift fork positions the shift collar and shift key. The shift fork is supported, both top and bottom, by nylon bushings for smooth operation and long wear (Fig. 117).

C. Keys

The operator controls movement of the shift fork by means of the gear selection control and cable. Note: There are no shift detents in or on the transmission on 1988 and newer mowers.
Removal - Toro Vacu Power/Lawn-Boy Medallion Models
Complete transmission removal on the Toro Vacu Power/Lawn-Boy Medallion mower is quite easy and is recommended for most self-propel system repairs. 1. Remove the spark plug lead from the engine to prevent accidental starting. Drain the fuel and oil. 2. Place the ground speed selector in neutral. This will make it easier to remove the speed selection cable later. 3. Remove the two anged head self-tapping screws securing the screen panel to the housing and remove the panel (Fig. 118). 4. Remove the black plastic transmission cover from the top rear of the housing. 5. Remove the two anged head self-tapping screws securing the belt cover to the top of the transmission. Pull the cable from belt guide and remove the belt guide. 6. Remove the transmission access cover from the rear of the housing by pressing from underneath. 7. Loosen the gear selection control cable clamp screw until the cable comes free. Do not attempt to remove the gear selection cable from the control arm at this time. 8. Turn the mower onto its right side and remove the four anged head self-tapping screws securing the end caps to the housing (Fig. 119).

9. Slowly pull the transmission from the housing being very careful not to damage the gear selection cable. Once clear of the housing, rotate the assembly until the cable can be safely removed.
Removal - Recycler/Rear Bagger Chassis
To remove the transmission from the chassis, raise the rear and support it with blocks. 1. Remove both rear wheels and wheel covers. 2. Remove the rocking key clutches (see Wheel Pinion Clutch on page 5-3). 3. Slide the pivot arm and spring arm off the axles. 4. Remove the belt cover. Loosen the belt guide and slip the belt off the pulley. Disconnect shift and clutch cables. 5. Slide the transmission to the right to slip the short end of the axle out of the chassis.

Fig 140

3428-0040
16. Slip the wheel, the original number of spacers, and the wheel cover onto the shoulder bolt and secure to the pivot arm using the nylon locknut. 17. Grease with No. 2 lithium-based grease. Use a hand grease gun to avoid excess pressure that may prevent the friction parts from working. As a rule, use two pumps to ensure that you do not over-grease. Be sure to grease after every 25 hours of use for maximum service life.
GEARCASE AND WHEEL ASSEMBLY, SPRING RATCHET STYLE

Fig 141

Spring Ratchet Style
The Spring Ratchet type wheel clutch system has been used on a wide variety of models. It consists of a spring supporting a drive key which engages the pinion. When the mower drive is engaged the axle turns the key which is engaged with an internal tooth on the pinion. The pinion turns the wheel gear. When the mower is pushed or turned, the pinion must rotate faster than the axle. As the pinion rotates it depresses the key, allowing the differential action. The axle drives both keys and pinions equally but they will ratchet individually. When the mower is pulled backwards, this type of clutch does not disengage. It will require the axle and transmission to turn backwards. It is critical to easy backing to make sure the self propel belt properly disengages.

WHEEL PINION SERVICE

The steps to service the wheel pinions are the same for both front and rear wheel drive models. 1. Raise the mower until the wheel is off the ground. Support with a block. 2. Remove the wheel bolt, wheel and wheel cover (Fig. 142).

Servicing the System

The things that can impede the function are dirt, rust or wear. The owners manual requires that ordinary engine oil be added to each side of the pinion periodically. This is to keep the anti seize from drying up. If that is not done, it will be necessary to remove the pinion, key and spring to clean and re-lubricate with anti-seize compound. On the left side there will be two keyed thrust washers and one regular thrust washer. Clean the end of the axle, keyway, and the parts removed. Inspect the key; if worn, replace. Make sure the thrust washers have the key tab on them. If the tab is broken, the pinion will tend to push the retaining rings out of their grooves. Lubricate the key, spring, and axle with anti-seize compound and reassemble. Note the pinion has the letter R stamped on one side and L on the other. If you are on the right side of the mower, the letter R should face you when you install the pinion. The letter L should be visible on the left side of the mower.

Fig 142

BBC / BOS / BCS

BLADE BRAKE CLUTCH SYSTEM (BBC)
There are two basic blade clutching system designs. The rst is commonly referred to as the BBC or Blade Brake Clutch. It has two versions which have been used on many Toro models as well as Lawn-Boy Medallion mowers. The second design was introduced in 2005 and is used on Toro (Blade Override System) and Lawn-Boy (Blade Clutch System) (Fig. 146 and Fig. 147). The blade clutch system offers the customer convenience to stop the blade while allowing the engine to continue to run. Before troubleshooting the BBC deck mechanism, be sure that it is adjusted properly. Refer to the BBC cable adjustment section for proper adjustments.

BBC Clutch Operation

The clutch operates by using a ywheel which turns with the engine crankshaft and a brake drum and blade that are free to turn separately from the ywheel. The two are connected by tensioning a drive belt between the ywheel and brake drum. The combination idler arm and brake controls the belt. When the control is engaged, the idler with the brake pad backs away from the brake drum and tightens the belt. When the control is released, a spring causes the idler to pivot towards the brake drum releasing the belt and engaging the brake. This stops the blade but allows the ywheel and crankshaft to continue to turn.
BBC Control Box Operation

Fig 146 3428-0001

The BBC control mechanisms purpose is to actuate the deck mechanism. It does this by tensioning and loosening the BBC cable. The control mechanism meets the federal governments 2-step blade engagement procedure. The traction drive can also be integrated with this control system.

Fig 147

3428-0004
The normal or at rest position of the control bar is indicated by the number 1 in the Figure 148. In order to engage the blade, the operator must rst cock the control bar down to position 2, then raise the control bar to position 3.

8. Slip the white nylon washer onto the J end of the buckling spring. The slotted side of the washer should face away from the end of the spring. Slip the spring into position in the rocker arm and the left control housing as shown in Figure 158. 10. Before installing the right control housing, check to make sure that both cable sheath ends are fully seated in their slots in the left housing. Also make sure that the sleeve passes through all components including the left control housing. Finally, make sure that the roll pin passes through the rocker arm and control bar. Install the right control housing and secure with the 2 nylon locknuts or 1 locknut and 1 ange nut.
11. Install the 3 anged head screws that retain the two control box halves. 12. Check for proper operation of the entire BBC system. Correct as required. 13. Bend the throttle control locking tab forward to provide positive lock with the throttle control and install the throttle control. 14. Adjust the BBC cable and traction cables as needed. See page 7-16.

9. Assemble the right control housing by installing the leaf spring and pin to retain the leaf spring (Fig. 159).

Ensure the transmission belt is disengaged, transmission tilted forward. Loosen the cable clamp on the handle. When you pull the cable down the Personal Pace/Easy Stride handle should raise to the stop. Hold the cable and secure the clamp (Fig. 243).

Lawn-Boy 2 Bail Handle

The 2 bail style is shown here (Fig. 244). The top bail is the engine stop. Release it and the ignition is grounded and a brake comes on to help stop the ywheel. The lower bail is the self propel bail. Squeeze it to tension the belt and drive the transmission.

Fig 244 Fig 243 DSC-4829

The engine stop cable is not adjustable. If it does not function, it must be replaced. The self propel cable is adjustable through a clamp. It should be adjusted so that lowering the bail about 1 (25mm) disengages the self propel. This is a gap that is comfortable for most operators.

Lawn-Boy Sens-a-Speed

On blade clutch models, the engine on and off is controlled by a switch on the left hand handle. The bail engages and disengages the blade. The Sens-a-Speed handle controls the self propel the same way as on a zone start model.
Handle Disassembly, Zone Start Models
1. Loosen the cable clamp and disconnect the Sens-aSpeed cable (Fig. 246).

Fig 245

DSC-4864a

A. Top bail

The Lawn-Boy Sens-a-Speed handle is made in two forms, zone start and blade clutch. The basic function is the same but the addition of the blade clutch mechanism makes the handle for those models a little more complex.

Fig 246 DSC-4869a

The top mounted bail is the engine stop control on zone start models and the blade control on blade clutch models. On a zone start model, pull the top bail down and hold to keep the engine running. The Sens-a-Speed handle telescopes and as it is depressed tensions the transmission drive belt. To operate this keep your elbows at your sides, hold your hands straight out in front of you and walk. If you want to go faster, walk faster. Do not push the Sens-a-Speed handle down. That will activate the drive too aggressively and the mower will jump forward.
2. Squeeze the ends of the upper bail to disengage them from the handle. On some models the right side of the bail may be connected to the pin by a push nut. The push nut can be removed or the bail removed with the pin attached (Fig. 247). 4. Slide the pin out of the left hand handle and pull the upper handle up and out. 5. The plastic sleeves will slide off the upper handle. 6. The springs can be removed from the top slides if necessary.
If the handle has been binding, clean the top slides and the sleeves before assembling. Dirt and grit in the sliding part of the handle can cause a bind. Assemble in reverse order. When you install the upper handle, line up the holes and install the pivot pins (Fig. 249).

Fig 265

348-0172

Fig 264

On BBC models, the control bail also controls the transmission belt engagement. The adjustment point is a knob about halfway between the control panel and transmission. Ideally, the cable should be set so that the transmission drive will disengage when the bail is lowered about 1 (25mm). This allows the bail to be lowered so that the wheels stop driving and the BBC remains engaged, but the gap isnt so large that the handle is hard to hold (Fig. 266). This measurement is not an exact requirement. It can be varied to accommodate a customer with small hands, etc.

Toro BOS Control

The BOS control is the upper bail on the handle. For the required 2 step engagement, there is a pivoting stop on the right hand handle. Rotate it out of the way and then pull the bail down for blade engagement (Fig. 267).
